There is provided a camera with an automatic focusing device having hybrid AF unit capable of always performing a reliable automatic focusing operation on a moving object to provide a more preferable photographic result. The camera includes first distance measuring unit 4 having at least a pair of light receiving sensors, for measuring the distance of an object by receiving a beam of light from the object, second distance measuring unit 3 having light projecting unit for projecting a beam of light upon the object and light receiving unit for receiving a beam of light reflected therefrom, for measuring the distance of the object by projecting a beam of light upon the object with the light projecting unit and by receiving a beam of light reflected therefrom with the light receiving unit and distance measuring method selecting unit 2 for selecting either the first distance measuring unit or the second distance measuring unit. The distance measuring method selecting unit is controlled such that it selects the first distance measuring unit when performing an automatic focusing operation which is most suitable for photographing a moving object.
